1. Don't trash your ideas!Alot of people trash their ideas after they get downvoted into oblivion. DON'T!!! Instead, keep it public so that the comments and downvotes will be available for future reference. Site staff can take a look at it and understand what ideas are bad and why. Keeping them untrashed also prevents duplicates. Just because your idea isn't loved by everyone doesn't mean it hasn't helped! Exploring new opportunities for improvement is ALWAYS a step in the right direction!
2. Mark as Exemplary!If someone in a Question thread has helped you, MARK IT AS THE TOP ANSWER! Doing so will generate 50-ish points on their account, improve their Exemplifications count, and will encourage them to keep being helpful in the future. Rewarding others for being good teammates is never a bad idea!
If someone ever forgets to mark your post as top answer and you feel you deserved it, don't be afraid to file a support ticket or kindly remind them. Just don't beg for it, point farming isn't cool.
